The system is described within a tight-binding framework, and transport properties are computed using the non-equilibrium Green\u2019s function formalism. We consider two junction configurations distinguished by the ring-wire coupling: a single-coupled junction and a double-coupled junction. In the single-coupled configuration, the coupling geometry alone breaks the spin symmetry, yielding a finite spin polarization (SP) even without any external field. The in-plane electric field further enhances the symmetry breaking in both configurations, serving as an efficient tuning parameter that drives the SP nearly\n                    <jats:inline-formula>\n                      <jats:tex-math>\n                        \n                      <\/jats:tex-math>\n                      <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" overflow=\"scroll\">\n                        <mml:mrow>\n                          <mml:mn>100<\/mml:mn>\n                          <mml:mi mathvariant=\"normal\">%<\/mml:mi>\n                        <\/mml:mrow>\n                      <\/mml:math>\n                    <\/jats:inline-formula>\n                    in the low-bias region. In the double-coupled configuration, spin symmetry is preserved in the absence of the external field, and the electric field acts as a sole source of symmetry breaking, producing a large SP. Finite temperature effects and different system sizes are examined, confirming the robustness of the observed features. To validate the findings over a wide parameter space, we considered different sets of parameters and found that the key signatures remain unchanged. Our results demonstrate that such hybrid structures are promising candidates for realizing an externally controllable spintronic device in low-dimensional systems.\n                  <\/jats:p>","DOI":"10.1088\/1361-648x\/aeb0fa","type":"journal-article","created":{"date-parts":[[2026,10,6]],"date-time":"2026-10-06T22:54:08Z","timestamp":1791327248000},"page":"425301","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Spin-dependent electron transfer through a ring-wire coupled junction: role of in-plane electric field"],"prefix":"10.1088","volume":"38","author":[{"given":"Prabhab","family":"Patra","sequence":"first","affiliation":[{"name":"Physics and Applied Mathematics Unit, Indian Statistical Institute"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3979-8606","authenticated-orcid":true,"given":"Santanu K","family":"Maiti","sequence":"additional","affiliation":[{"name":"Physics and Applied Mathematics Unit, Indian Statistical Institute"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]}],"member":"266","published-online":{"date-parts":[[2026,10,20]]},"reference":[{"key":"cmaeb0fabib1","doi-asserted-by":"publisher","first-page":"25","DOI":"10.1038\/s44306-024-00029-0","type":"journal-article","volume":"2","author":"Din","year":"2024","journal-title":"npj Spintron."},{"key":"cmaeb0fabib2","doi-asserted-by":"publisher","first-page":"10","DOI":"10.1038\/s44306-024-00070-z","type":"journal-article","volume":"3","author":"Xie","year":"2025","journal-title":"npj Spintron."},{"key":"cmaeb0fabib3","doi-asserted-by":"publisher","first-page":"1488","DOI":"10.1126\/science.1065389","type":"journal-article","volume":"294","author":"Wolf","year":"2001","journal-title":"Science"},{"key":"cmaeb0fabib4","doi-asserted-by":"publisher","first-page":"323","DOI":"10.1103\/RevModPhys.76.323","type":"journal-article","volume":"76","author":"Zuti\u0107","year":"2004","journal-title":"Rev.
